B1207-PASSENGER AIRBAG INDICATOR CIRCUIT SHORTED TOGETHER





For a complete wiring diagram, refer to the Wiring Information Electrical Diagrams.

- When Monitored:
With the ignition on.

- Set Condition:
When the Occupant Restraint Controller (ORC) detects over current on the Indicator Driver circuit.





1. VERIFY ACTIVE DTC

NOTE: Ensure the battery is fully charged.

1. Turn the ignition on.
2. With the scan tool, read ORC DTC.

Does the scan tool display active B1207-PASSENGER AIRBAG INDICATOR CIRCUIT SHORTED TOGETHER DTC?

Yes

- Go To 2

No

- Go To 5

2. CHECK (G104) PASSENGER AIRBAG INDICATOR DRIVER CIRCUIT FOR A SHORT TO (F201) FUSED IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT





WARNING: Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.

1. Remove the Totally Integrated Power Module (TIPM) Fuse 21.
2. Disconnect the ORC harness connectors.
3. Disconnect the Passenger Airbag ON/OFF Switch harness connector.

NOTE: Check connectors - Clean and repair as necessary.

4. Connect the SRS Load Tool Adapter 8443-25 to the ORC harness connectors.
5. Measure the resistance between the (G104) Passenger Airbag Indicator Driver circuit cavity 3 and the (F201) Fused Ignition Switch Output (Run-Start) circuit cavity 4 in the Passenger Airbag ON/OFF Switch harness connector.

Is the resistance below 100.0 ohms?

Yes

- Repair the (G104) Passenger Airbag Indicator Driver circuit for a short to the (F201) Fused Ignition Switch Output (Run-Start) circuit.
- Perform the ORC VERIFICATION TEST. Occupant Restraint Controller (ORC) Verification Test.

No

- Go To 3

3. CHECK (G104) PASSENGER AIRBAG INDICATOR DRIVER CIRCUIT FOR A SHORT TO VOLTAGE





WARNING: Turn the ignition on, then reconnect the 12-volt battery. Failure to follow these instructions may result in possible serious or fatal injury.

1. Measure the voltage of the (G104) Passenger Airbag Indicator Driver circuit between the Passenger Airbag ON/OFF Switch harness connector cavity 3 and ground.

Is there any voltage present?

Yes

- WARNING: Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.

- Repair the (G104) Passenger Airbag Indicator Driver circuit for a short to voltage.
- Perform the ORC VERIFICATION TEST. Occupant Restraint Controller (ORC) Verification Test.

No

- Go To 4

4. CHECK FOR ACTIVE DTC B1207-PASSENGER AIRBAG INDICATOR CIRCUIT SHORTED TOGETHER WITH PASSENGER AIRBAG ON/OFF SWITCH DISCONNECTED

WARNING: Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.

1. Remove the SRS Load Tool Adaptor 8443-25 from the ORC harness connectors.
2. Reconnect the ORC harness connectors.

WARNING: Turn the ignition on, then reconnect the 12-volt battery. Failure to follow these instructions may result in possible serious or fatal injury.

3. Turn the ignition off, wait 10 seconds, and then turn the ignition on.
4. With the scan tool, read ORC DTC.

Does the scan tool display active B1207-PASSENGER AIRBAG INDICATOR CIRCUIT SHORTED TOGETHER DTC?

Yes

- WARNING: Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.

- WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to follow these instructions may result in possible serious or fatal injury.

- Replace the ORC.
- Perform the ORC VERIFICATION TEST. Occupant Restraint Controller (ORC) Verification Test.

No

- Replace the Passenger Airbag On/Off Switch.
- Perform the ORC VERIFICATION TEST. Occupant Restraint Controller (ORC) Verification Test.

5. TEST FOR INTERMITTENT CONDITION
1. With the scan tool, record and erase all DTC from the ORC.
2. If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.

WARNING: Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.

3. Using the wiring diagram/schematic as a guide, inspect the wiring and harness connectors.
4. Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.
5. The following additional checks may assist you in identifying a possible intermittent problem.
6. Reconnect any disconnected components and harness connector.

WARNING: Turn the ignition on, then reconnect the 12-volt battery. Failure to follow these instructions may result in possible serious or fatal injury.

7. With the scan tool, monitor active codes as you work through the following steps.

WARNING: Maintain a safe distance from all airbags while performing the following steps. Failure to follow these instructions may result in possible serious or fatal injury.

8. Wiggle the wiring harness and harness connectors of the related airbag circuit or component.
9. If only stored codes return, continue the test until the problem area has been isolated.
10. In the previous steps you have attempted to recreate the conditions responsible for setting the active DTC in question.

Does the scan tool display any ACTIVE DTC?

Yes

- Perform the appropriate diagnostic procedure. Testing and Inspection.

No

- No problem found at this time. Erase all codes before returning vehicle to customer.
